Description

Clamping clip

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a clip, and more particularly, to a clip that can easily be used by a woman or a weak person with weak strength by improving the clip to use a strong force and a large force.

In general, the clip is used for various purposes such as office work and the like around us. An example of a typical clip clip is disclosed in Korean Utility Model Registration No. 20-0205297.

1, the plate member is bent so that the free ends (openings) of the upper member 1 and the lower member 3 are elastically deformed in the direction in which the free ends (openings) So as to generate a restoring force. Hand grip levers 4 that apply an external force in a direction opposite to the elastic restoring force of the upper member 1 and the lower member 3 are coupled to the upper member 1 and the lower member 3. [ The handlebar lever 4 is rotatably coupled to the upper member 1 and the lower member 3. The handlebar lever 4 has a point b as a boundary between the elastic shaft member 2 and the upper member 1 or the lower member 3 as a point of action b, A fulcrum c is formed so that an external force can be applied to the free end of the claw lever 4 protruding outwardly of the main body. The pawl clips are configured such that a pair of the handle levers 4 rotated by the upper member 1 and the lower member 3 are coupled to the opening h of the main body. When the hand grip levers 4 respectively coupled to the upper member 1 and the lower member 3 are simultaneously clamped and compressed, the clamp clip openings (inlet h) are opened to hold the documents or hold the objects . At this time, when the pressing force applied to the handlebar lever is released, the gripper clip is elastically restored and the fixing is completed.

2 and 3, the ratio of the distance d between the fulcrum a and the point b to the distance e between the fulcrum a and the point c is about 1 : 1 ratio.

Since the clip of this structure has a principle of picking up a document or an object by using a strong elastic restoring force, a large force is required to control a strong elastic restoring force. Therefore, the conventional clip has a problem that it is impossible or inconvenient to use a weak woman or a weak person.

The gripper clip 4 is excessively large and excessively covers the surface of the document or object when folded after use, which is inconvenient. In addition, since the gripper clip 4 is large in size, the material is wasted and the gripper clip is not economical. Since the clip has a large volume during packaging, the manufacturing cost is high. Since the gripper clip 4 is coupled to the gripper mouth, the gripper clip has a thick gripper mouth, which makes it difficult to carry out delicate work.

Despite the many problems associated with such conventional clip, manufacturers and vendors have not addressed this problem. In addition, the financial loss due to the rise in product prices and the inconvenience of use are all transferred to consumers.

Referring to Figs. 5 to 10, the clip clip 10 according to the first embodiment of the present invention is a clip clip capable of holding a document or an object. The clamping clip 10 includes an elastic shaft member 40, an upper member 20, a lower member 30, a handlebar lever 70, a hinge 60, an assembling hole 62, And includes a receiving portion 50.

The elastic shaft member (40) is formed on one side of the clip (10). The elastic shaft member 40 is connected to one end of the upper member 20 and the lower member 30, which will be described later.

The upper member 20 is a cantilever-shaped member. One end of the upper member 20 is connected to a boundary line of the elastic shaft member 40. The upper member 20 may be integrally formed with the elastic shaft member 40.

The lower member (30) is connected to the elastic shaft member (40). The lower member 30 is disposed symmetrically with the upper member 20 with respect to the elastic shaft member 40. The lower member 30 is a cantilevered member. One end of the lower member 30 is connected to a boundary line of the elastic shaft member 40. The elastic shaft member 40, the upper member 20, and the lower member 30 constitute a triangular columnar appearance in the state in which an external force is not applied. The upper end of the upper member 20 and the free end of the lower end 30 are disposed so as to generate an elastic restoring force in a direction in which they approach each other. The elastic restoring force acting on the upper member 20 and the lower member 30 is generated by the elastic shaft member 40.

The upper member 20, the lower member 30, and the elastic shaft member 40 may be made of metal or synthetic resin. For example, carbon steel and stainless steel may be used as the metal material, and polypropylene, acrylobutadiene styrene and the like may be used as the synthetic resin material.

The pair of hand grip levers 70 are provided. The handlebar levers 70 are installed on the upper member 20 and the lower member 30, respectively. The handlebar levers 70 are rotatably mounted on the upper member 20 and the lower member 30, respectively. The handlebar lever 70 is a kind of cantilevered member. The handle leverage 70 is rotatably coupled to a hinge portion 60 described later. The handhold leverage 70 has a hinge shaft 72 that is coupled to the handhold leverage 70. The pair of hinge shafts 72 may be symmetrically arranged.

The hinge portion 60 is a portion where the handlebar lever 70 is engaged with the upper member 20 and the lower member 30. The hinge portion 60 is provided on the upper member 20 and the lower member 30, respectively. The hinge portion 60 is formed by plastic deformation so that the surface of the upper member 20 or the lower member 30 partially protrudes outward without being cut. The hinge portion 60 is formed by stamping the surface of the upper member 20 or the lower member 30 with a mold so that the hinge portion 60 is not cut. The hinge portion 60 plays an important role in forming and maintaining a firm fixing force on the free end portions of the upper member 20 and the lower member 30. The hinge unit 60 is configured to sufficiently maintain the rigidity of the upper member 20 and the lower member 30 even when an external force is applied to the handlebar lever 70, Thereby providing an assembler 62. The hinge portion 60 is formed by plastic deformation without cutting the upper member 20 and the lower member 30 so that the hinge portion 60 is deformed by work hardening and plastic working The cross-sectional strength is increased to transmit the external force directly to the upper member 20 and the lower member 30 without being damaged even if the force applied by the grip lever 70 is concentrated. That is, although the hinge portion 60 is long from the boundary line of the elastic shaft member 40 to the free end (inlet) of the upper member 20 and the lower member 30, the elastic shaft member 40 The elastic restoring force generated by the hinge part 60 is prevented from being lost due to the structure of the hinge part 60 reinforced by the rigidity, so that the elastic restoring force is well transmitted to the free end of the upper member 20 and the lower member 30. Further, since the hinge portion 60 is structured to receive a material for deformation in a relatively large area as compared with the conventional structure, there is an advantage that a defective rate in processing is low. In addition, the hinge portion 60 is simple in the manufacturing process and is excellent in workability, so that productivity is improved.
5 or 11, the hinge unit 60 may be disposed so as not to be directly connected to the outer edges of the upper member 20 and the lower member 30.

The assembling hole 62 is formed on a side surface of the hinge portion 60. The assembly hole 62 is a hole penetrating the side surface of the hinge portion 60 formed by plastic deformation. The pair of the assembling holes 62 may be provided. A hinge shaft (72) of the handlebar lever (70) is rotatably inserted into the assembly hole (62).

The assembling hole 62 is formed between the free end 25 of the upper member 20 and the lower member 30 and the boundary line between the elastic shaft member 40 and the upper member 20 and the lower member 30. [ . The assembling hole 62 serves as a point of action b of the handlebar lever 70.

For example, the hinge portion 60 may form a triangular surface with the side where the assembly hole 62 is formed. The surface on which the assembling hole 62 is formed is formed so that the inclination of the side in the direction of approaching the elastic shaft member 40 about the assembling hole 62 is steeper than the inclination of the side in the direction away from the elastic shaft member 40 .

The hinge unit 60 may be formed on the upper member 20 and the lower member 20, respectively, as shown in FIG. The hinge portions 60 may be formed on the upper member 20 and the lower member 20, respectively, as in the second embodiment shown in FIG.

The projected support portion 50 is formed on the upper member 20 and the lower member 30, respectively. The protruding support portion 50 is disposed between the hinge portion 60 and the elastic shaft member 40 and the boundary line between the upper member 20 and the lower member 30. More specifically, the protruding support portion 50 is disposed at a position between a boundary line between the assembling hole 62 and the elastic shaft member 40. The projected support portion (50) constitutes the fulcrum (a) of the handlebar fulcrum (70). The protrusion receiving portion 50 is formed to protrude outward from the surface of the upper member 20 and the lower member 30. The protrusion receiving portion 50 is formed in a straight line shape extending in a direction parallel to the boundary line between the elastic shaft member 40 and the upper member 20 and the lower member 30. The protruding support portion 50 may be formed in the form of a linear shaping bead. The protruding support portion 50 prevents the middle portion of the handlebar lever 70 from directly contacting the surfaces of the upper member 20 and the lower member 30. [ The protruding support portion 50 prevents the handlebar lever 70 from interfering with the boundary line of the elastic shaft member 40 when an external force is applied to the free end portion of the handlebar lever 70, The upper member 20 and the lower member 30 can be easily opened by applying a force to the hinge shaft 72 assembled to the assembling hole 62 with respect to the projecting fulcrum point a. . The protrusion receiving portion 50 may be formed on the upper member 20 and the lower member 30, respectively, as shown in FIG. 5 and 13, a plurality of protrusion receiving portions 50 may be formed on the upper member 20 and the lower member 30, respectively.

The handle leverage 70 has an angle θ formed between the upper member 20 and the lower member 30 in a state of being in contact with the protruding support portion 50 of 5 ° to 60 ° As shown in Fig. When the angle θ formed between the handlebar lever 70 and the surface of the upper member 20 or the lower member 30 is less than 5 °, the problem of the role of the projecting support portion 50 is not realized properly have. On the other hand, when the angle θ between the handlebar lever 70 and the surface of the upper member 20 or the lower member 30 exceeds 60 °, the user applies a compressive force to the handlebar lever 70 There is a difficult problem. That is, there is a problem that it is difficult to apply a compressive force to the free end portions of the pair of pull lever levers 70.

7, the clip clip 10 according to the present invention employs a structure in which the principle of the leverage is applied optimally so that the distance d between the fulcrum a and the fulcrum b, ) And the force point (c). (E) The larger the ratio, the greater the force at the point of action (c)

The clip clip 10 according to the present invention increases the proportion of the distance e between the fulcrum a and the force point c relative to the distance d between the fulcrum a and the point b, (B), it is possible to use a force as large as a proportional force at the point of action (b). To this end, the position of the assembly hole 62, which is the engagement position of the handlebar lever 70, is changed to a position near the boundary line of the elastic shaft member 40. Accordingly, it is possible to reduce the length of the grip lever 70 to a great extent, thereby reducing the waste of unnecessary materials at the time of manufacturing the product, thereby reducing the manufacturing cost. Even if the length of the grip lever 70 is reduced, there is no great problem in using the clip.

The thickness of the conventional clip clip inlet (opening), which is thick by changing the engagement position of the pull lever 70, can be greatly reduced, the opening of the clip clip 10 of the present invention can be thinned to enable delicate work, 10) can be used more diversely.

In the clip clip 10 according to the present invention, the handlebar lever 70 does not cover documents or objects, and the amount of covering is small even if a covering situation occurs. 3 and 4, the handle barrel 70 is excessively long, so that the entire handle bar 70 covers the top of the document and covers the article so that when the user turns the page of the document There is an inconvenient problem. In this case, the user may pull out the handle lever. In this case, there is a problem that reuse of the clip is difficult. The present invention has the effect of solving the problem of the conventional structure.

11, the clip clip 10 according to the second embodiment of the present invention is configured such that the hinge portion 60 is engaged with the upper member 20 and the lower member 30, respectively, as compared with the first embodiment described above, And has the same configuration as that of the first embodiment except that the above-described projecting support portion 50 is not formed. The second embodiment can be easily understood with reference to the first embodiment described above, except for the configuration related to the protruding support portion 50, so that detailed description will be omitted.

In the second embodiment, the fulcrum point (a) of the handlebar fulcrum 70 is the boundary line of the elastic shaft member 40. [ In the case of the second embodiment, since the boundary line of the elastic shaft member 40 forms a curved surface when a compressive force is applied to the handlebar lever 70 relative to the first embodiment, intuitive force transmission The rigidity of the upper member 20 and the lower member 30 is sufficiently secured owing to the structure of the hinge portion 60 and the assembling hole 62 provided in the hinge portion 60 is not sufficient, Is moved from the free end of the upper member 20 and the lower member 30 toward the elastic shaft member 40 so that the upper member 20 and the lower member 30 The open end of the free end portion of the guide plate can be opened.

12 and 13, the clip clip 10 according to the third embodiment of the present invention is similar to the first embodiment except for the configuration of the elastic shaft member 40, And has the same configuration. Accordingly, only the elastic shaft member 40 of the clip clip 10 according to the third embodiment will be described in detail, and the rest of the structure will be described with reference to the first embodiment.

The elastic shaft member 40 of the clip clip 10 according to the third embodiment is composed of a plurality of members. The elastic shaft member 40 includes an upper hinge member 42, a lower hinge member 44, an elastic center shaft 48, and an elastic plate 80.

The upper hinge member 42 is formed by bending the upper member 20. A central shaft hole 46 is provided at the lower end of the upper hinge member 42. The central shaft hole 46 is disposed in a direction parallel to the boundary line between the upper member 20 and the upper hinge member 42.

The upper hinge member 42 and the lower hinge member 44 of the elastic center shaft 48 are inserted into the central shaft hole 46 with the central shaft hole 46 disposed on the same axis. The upper hinge member 42 and the lower hinge member 44 are rotatably coupled to each other about the elastic center shaft 48.

The elastic plate 80 is a member that acts as a kind of spring for generating an elastic restoring force on the upper hinge member 42 and the lower hinge member 44. One end of the elastic plate 80 is coupled to the upper member 20 and the other end of the elastic plate 80 is coupled to the lower member 30. The elastic restoring force of the elastic plate 80 generates an elastic restoring force in a direction in which the free end of the upper member 20 and the free end of the lower member 30 are brought close to each other.

The forceps of the upper member 20 and the lower member 30 are sufficiently secured due to the structure of the hinge portion 60 described above with reference to the first embodiment of the clamp clip 10 according to the third embodiment, Since the assembly hole 62 provided in the hinge portion 60 is arranged to move from the free end of the upper member 20 and the lower member 30 toward the elastic shaft member 40, Thereby providing the effect of opening the free end of the upper member 20 and the lower member 30. [

In addition, the constitution of the protruding support portion 50 is different from that of the first embodiment in that the constitution of the protruding support portion 50 is formed for each of the upper member 20 and the lower member 30, and the other components are the same as those of the first embodiment.

As described above, in the clamping clip according to the present invention, the clamping pawls according to the present invention are arranged such that the hinge portion, which is the point of action of the pulling lever, moves from the free end of the upper member and the lower member toward the boundary line of the elastic shaft member, The distance between the upper end and the lower end of the lower member is larger than the distance between the upper end and the lower end. Accordingly, it is possible to easily use a woman or an elderly person who has weak power when arranging office documents or picking up objects. In addition, since the amount of protruding outwardly of the handlebar levers is small, it is possible to solve the major disadvantages of the conventional clip for covering documents and the surface of the product, to reduce the waste of materials, Effect. Further, the clamping clip according to the present invention can reduce the thickness of the clamping clip inlet by forming the hinge portion at a position spaced from the free end of the upper member and the lower member, thereby providing a delicate working effect. INDUSTRIAL APPLICABILITY The clip clip according to the present invention is easy to use, has a strong fixing force, and is affordable, thereby providing a consumer with a clip clip having a high degree of satisfaction.
